SKATE-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 59'7,163, dated January11, 1898. Application filed Aprl 1, 1897. Serial Ne. 630315. (Nomodai Toall whom it may oonoern:

Be it known that I, HERBERT XV. B. GOWDY, a citizen of the UnitedStates, residingat Union Pier, in the County of Berrien and State ofMichigan, have invented certain new and useful Inprovements inSkate-Sharpeners; and I do herehy declare the following to be a full,clear,'and exactdescription of the invention, su eh as will enableothers skilled iii the art to which it appertains to make and use thesame.

My invention appertains to skate-sharpeners, and relates moreparticularly to a device adapted for holding a section or piece of file,preferably having a flat and convex side.

My improved sharpener consists in the construction and combination ofparts, as will be hereinafter fully described and claimed, referencebeing had to the accompanying drawings, in which- Figure 1 is a top planView of my invention complete, showing the members thereof ad- Fig.` 2is an end elevation showing the file so adjusted as to present itsconvex face. Fig. 3 is a similar View showing the file a'djusted topresent its fiat face. Fig. i is a central longitudinal section of Fig.1.

For convenience of reference to the various details involved they willbe indicated by figures, the same figure being applied to the, same partthroughout the several views.

Briefly stated, my invention may be said to consist in providing aholder which is laterally adjnstable, enabling the jaws thereof toaccommodate varying widths of runners, and also of certain accessoriesdeemed necessary to hold the parts in their adjusted positions Referrngto the drawings, l and 2 represent the holding members of myskate-sharpener. Said members consist of the jaws proper, 3, designed tolie upon either side of the skate-runner, receivin g the same betweenthem. The upper ends of said members term'i-nate in the lateral bend orhead i and 5, respectively, the head 4 being provided upon its uppersurface with the recess 6, having the end guideways 7, while the head 5is provided with the laterally-extending flange or body 8, designed tobe received by the recess 6 and held therein by the guideways 7. (Moreclearly shown in Figs. 1 and l.)

In order that the j aws may be held in an adjusted position with respectto each other, I provide the set-screw 9, which is seated in a threadedapertnre provided in the recess 6 after first passing through theslotted opening 10, centrally fol-med in the fiange S. By thisarrangement it will be readily apparent that the jaws may be separatedor drawn together and held in the desired position by simply turninghome said set-screw.

The holding` members 1 and 2, it will be observed, are also providedupon their inner faces with the offset or open section 11, designed toprovide a seat 173 for the file 13, and in order that said file mayalways be held in its seat in such position that the plane thereof willbe parallel With the edge of the jaws I locate upon one end of each ofthe seats 12 the guide-block 14, preferably formed integrally with thejaws, the inner face of which is inclined upwardly and inwardly, as moreclearly shown in Fig. 4. By this construction it will be readilyapparent that said guide will always direct the end of the filedownward, no matter what the thickness thereof may be, thus holding thesame in position to receive the bottom edge of the shate-runner as it isplaced between the jaws.

Upon the end of member 2 I locate the bracket or lip 15, preferablyintegrally formed with said member. Mounted in a suitablythreadedaperture in said bracket I locate the thumb-screw 16, designed to takeentirely through said bracket and engage with the free end of the file,and as said screw is directed inwardly the action thereof will be toforce the file inward and also lock it securely in position upon theseats 12, preventing any lateral or longitudinal movement.

It will of course be un derstood that the parts forming my improvedskate-sharpener maybe construoted of any preferred and suitablematerial, though it is thought that best results will follow when a lowgrade of cast metal is employed, rendering it possible to cheaply andexpeditiously produce the de- Vice.

The operation of my improved skate-sharpener may be stated to be asfollows: After the parts are assembled in their respective operativepositions and a section of a file placed IOO 2 &7,163

upon the seats 12 the adjusting-screw 9 is loosened, when the jaws maybe separated sufficiently to loosely receive between them the runner ofthe skate, when said screw is turned home in its seat, thus binding theparts firmly together. The thumb-screw 16 is then turned tightly againstthe end of the file, when the sharpener may be appled to theskate-runner by simply reciprocating the same thereon until the desiredresult is produced, enabling the device to beefiectively used by anyone, even though not skilled in the work.

lt will of course be understood that if a face which shall be at rightangles to the walls of the runner isdesired the fiat surface of' thefile will be exposed. If, however, it is desired that the bottom of therunner shall present a coneave face, of course the convex side of thefile will be presented.

It Will be seen from the foregoing that I have produced a simple, cheap,and efficient skate-sharpener, and believing the Construction andoperation thereofwill be fully apparent furtherreference is deemedunneces sai-y.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. A skate-sharpener consistingof adjustable jaws, one jaw having a groove in each end, and the otherjaw fitting said groove, and means to fasten the jaws, as set forth.

2. A skate-sharpener consisting of adjust able jaws, one having adepressed portion on its top surface, and the other jaw sliding in ablejaws, having a tongue-and-groove joint,

and means to hold the jaws in any desired position, as set forth.

5. A skate-sharpener consisting of adjustable tongu eand-grooved j awshaving depending parallel 'extensions to receive the runner of a skate,and` a file carried on the upper shoulders of the extensions, and meansto hold the file in place, as set forth.

6. A skate-slarpener conssting ofadjustable jaws, each j aw having atriangular guideblock at one end,`and means to force a file against saidblock and hold it in place, as set forth.

7. A skate-sharpener consisting of adjustable jaws having atongueandgroove joint, one of the jaws having a longitudnal extensioncarrying a set-screw adapted to press against a file and hold it inplace, as set forth.

In testimony whereof I afix my signature in presence `of two witnesses.
